Hello,
What is the brand name and model of your printer? Make sure that your ink cartridges are precisely the correct cartridges for the brand and model that you are using. From what I have experienced ... if you try to use a used ink cartridge you will recieve an error.

If a brand new ink tank is not recognized, it has a faulty chip. I took the chip off the faulty tank and replaced it with another one. That worked for me.

I had the same problem. My mp630 is also only 4 months old. I replaced all colour ink cartrdiges(inc black), but was only able to release the function for detecting the ink levels for magenta and cyan. Yellow and black then started giving error message U043, with them alternating between working, but never working at the same time. Getting them all clicked in with the lights glowing red does not solve the problem, as once the printer cover is closed, the same error message turns up. The only thing that worked for me is moving the chip slightly out of alignment, by pushing the sliding chip holder, and I only had to do this twice before they all started working and the printer was unlocked.

Dear Sir, Thank you for answering. I phoned my comp. expert.He took the canon printer, as well as the previous canon printer, ( one which I used for about six months when it decided not to print) and I hope he can fix at least one of them before end of day.
Usually, and because of deadlines, etc. I pop out and buy a new one which is easier and faster and sometimes cheaper. I like to work real hard and I have to, but, I hate battling for hours on end with stuff that refuses to talk back to me. Now you can also see that I am a BBC baby.
Born Before Computers etc. and no patience.
Kind regards,
Wiebre
